Now "Nothing Compares 2 U" singer O'Connor has removed herself from the website after receiving a barrage of criticism from her online followers.

She tells V Magazine, "I've stopped Twitter now because, although it was fun for a while, I had to stop because I was getting too much abuse. Some people just take things so seriously, and things I was being funny about they would take terribly seriously.

"Plus, it's a bit of an addiction; you got to stop it at some point and get on with living."

In September, O'Connor sparked fears for her health after she wrote a Twitter message which suggested she was feeling suicidal. She later assured fans she had no plans to take her own life and wrote an open letter discouraging suicide.
